Rack-Mounting

If you need or prefer to rack mount your amplifiers, contact your
Mark Levinson dealer about the optional rack mount kit. This
purpose-designed assembly provides the needed ventilation for
the heat sink “chimneys” of the amplifiers, as well as the support
required for this heavy component.
To use the rack mount kit, simply bolt the shelf securely to the
rack, remove the four feet from the bottom of the amplifier, slide
the amplifier into place, and then secure the amplifier to the shelf
using the two remaining screws provided with the kit. Slots on
the rear of the shelf may be used for dressing cables or using cable
ties.
The drawing below will help you visualize the assembly.
The mounted Nº432 amplifier and rack mount kit occupies four
standard rack units of height. The Nº431 amplifier and rack kit
takes up three standard rack units of height.
